IMPROVEMENT IN WATER-WHEELS.

I, THOMAS LEFFEL, of Springfield, in the county of Clark and State of Ohio, have invented a new and useful Improvement in Water-Wheels, of which the following is a specification.

Nature and Objects of the Invention.

The nature of iny'invention relates to the construction of a case for a water-wheel by means of which a wheel adapted to be used-as a horizontal or turbine water-wheel may be'fitted to'the pen-stock upon a horizontal shaft and operated asa vertical wheel, and the water all allowed to be discharged from the wheel through the opposite ends of the case and carried off by proper draught-tubes; and consists in constructing the case in such a manner that the draught-tubes may be readily attached to it and the pen-stock at either end, and so that the wheel can be removed from the case at either end by removing only one of the draught-tubes, without disturbing the setting of the case.

This invention further consists in constructing the case for a water-wheel in sectional parts, which are connected together by means of screw-bolts, so that, after the wheel and case are attached to the draughttubes and pen-stock, the sectional parts may be removed for repairs or adjustment without removing the wheel-case and draught-tubes entire.

Description of the Accompanying Drawing. Figure 1 is a perspective view of the case and wheel. Figure 2 is a vertical section through the center of the wheel, case, and tube, set in the pen-stock.

Figure 3 is another plan of fig. 2, showing a different setting of the wheel in the pen-stock.

General Description.

' E is a bridge, secured to the case by bolts, and to which are attached journal-boxes, It, for the shaft A to work in.

P P is the pen-stock, in which the wheel is set.

H H show the proper place to put shores orstuds attached to the bottom of the pen-stock, and made to extend up to the pointwhere it is desired to place the wheel, and are used to relieve the sides of the penstock tubes from the weight of the wheel and case.

T T are draught-tubes, and may be of metal or wood, and can be made square and secured to the flanges G G by bolts.

S S are stufling-boxes, water around the shaft.

to prevent the escape of Fig. 2 shows the wheel iuclosed in a pen-stock, with the draught-tubes T 1 inside of the pen-stock, and 'is a convenient mode of setting in an old pen-stock which is too large for the wheel.

, Fig. 3 is the preierredplan, as it enables the wheel to be removed at either end by taking out one of the tubes T and removing the bridge E and journal K.

The case also, being'made by bolting several parts,

can be removed in sections without disturbing the remainder, setting on shores placed under the case H H, as described.

The joints of the pen-stock P P and the tubes T T should be water-tight, and extend down into the tail-water.

The water en ers through the chutes D and is discharged through the tubes '1 'l, as indicated by arrows.

The construction of the wheel adapted to be used in the case is full y described in Letters Patent granted me January 16, 1868; any similar wheel, however, may be employed in its stead.

Claims.

I claim as my invention- 1; A wheel-case composed substantially of the cylinders B B, flanges G O and G.G', chutes D, and

bridge E, adapted to be used upon a horizontal shaft,
